Effect of Extraction Time on the Extractability and Physicochemical Properties of Pepsin-Soluble Collagen (PCS) from the Skin of Silver Catfish ( sp.).

The current study aimed to determine the effects of extraction time on the extractability and physicochemical properties of collagen from the skin of silver catfish ( sp.). Pepsin soluble collagen (PSC) was extracted for 24 and 48 h and analysed in terms of chemical composition, solubility, functional group, microstructure, and rheological properties.
